NON-REFILLABLE BOTTLE.

Specification of Letters Patent.

Patented July 1d, 1914.

Application filed July 31, 1918. Serial No. 782,276.

To all whom it may concern:

Be it known that we, JEREMIAH C. LAUTENBAGHER and ALBERT GEARY, citizens of the United States, residing at Schuylkill Haven, in the county of Schuylkill, State of Pennsylvania, have invented certain new and useful improvements in Non-Refillable Bottles, of which the following is a description, reference being had to the accompanying drawing and to the figures of reference marked thereon.

Our invention relates to improvements in non-refillable bottles, the object being to provide a simple, effective and easily assembled device to be secured in the neck of the bottle, having suitable arrangement of valves to allow ready emptying of the receptacle when in emptying position, but antomatically closing the inlets to the body of the bottle at all times,under pressure from without, and furthermore, so constructed as to prevent the insertion of any tool which might be used in an attempt to tamper with the valves.

The invention, therefore, consists in the matters hereinafter described and referred to in the appended claims.

In the drawings, Figure 1 is a vertical section through the upper part of a bottle with our improved device secured therein; Fig. 2 is a similar view with the parts of our improved device in the position when the contents of the bottle are being poured; Fig. 3 is a view similar to Fig. 1 with the bottle in a substantially horizontal position, illustrating the closed position of the valve should an attempt be made to refill the bottle while in this position; and Fig. l is a detail cross sectional view on the line H of Fig. 1.

Referring to the drawings our improved device is constructed in the form of an elongated stopper, which is secured within the neck 2 of a vessel or bottle 3 and spaced therefrom, as shown. The stopper is of a sufficient length to extend well into the body of the bottle, and is designed to allow the contents thereof to pass out of the bottle when turned in a pouring position, as will be presently described. This stopper is composed of two sections 4: and 5, secured to each other by the screw thread 6.

The section 4, which will be referred to as the upper one, is provided near its top with an annular recess 7. Opposite this recess is a similar annular recess 8, formed in the neck of the bottle. Into this annular groove formed by the mating recesses in the stoppersection and the neck of the bottle is sprung a split ring, 9. This ring is put in place when the stopper is forced into the neck, and forms permanent securing means against the removal of the stopper and its other working parts. A sealing material 10 may be used to hold the head 11 of the section 1 firmly-against the upper edge of the bottle.

The upper section 4 is of tubular formation, and midway its length is provided with. a wall or partition 12, which prevents the insertion of a tampering tool. This partition forms two compartments 13 and 14;, the upper one of which is provided with the discharge openings 15, annularly disposed. thercin, and the lower one of which is formed with elongated openings lo extending between the ribs 17. Operating within the lower compartment 14 is a cupped member 18, hollowed out as shown and adapted to receive the weight or ball 19. An extension 20 is provided on the under side of the said member, and holds one end of a spring 21, which latter in turn operates upon the valve 22 to keep the latter on its seat This valve 22 is recessed at 23, and receives the other end of the spring 21. An

annular shoulder 2a is formed upon the valve, and, as shown in Fig. 1, rests upon the valve seat 25, formed on the upper edge of the lower section 5 of the stopper. stem 26 extendsfrom the valve, and is pro vidcd with the head 27. This head is designed to receive an impact from a weight or ball 28, contained in the lower section 5, when the bottle is inverted for pouring. It also serves to guide the valve, and at the same time not interfere with the passage of the contents. In this lower section 5, openlugs 29 are formed between the ribs 30. These openings direct the initial discharge of the contents when the bottle is inverted stopper, a valve seat formed on the lower,

stem 26 of the valve. The valve is de-" rows, air passing into the bottle in the reverse direction and through the diametrically opposite opening.

As shown in Fig. 3, the valve is held closed when the bottle is placed in a horizontal position. This is effected through the spring 21 exerting a force in two direct-ions, i. 6., the spring when not afiected by either of the ball weights 19 or 28, is permitted to expand, and close the valve 22 and position the member 18 tight against, the partition 12. The passage of any liquid either in an outgoing or an incoming direction, is thus prevented. 7

From the foregoing, it will be obvious that a highly efiicient device isprovided, the working parts of which are few and easily assembled and readily inserted within the neck of a bottle.

Many mechanical changes may be made in the construction of ourdevice, without departing from the scope of our invention, and hence we do not wish to be limited to the exact construction set forth.

Having thus described our invention, what wec-laim as new and desire to secure by Letters Patent, is:

1. In combination with the bottle, an emptying stopper inserted therein and com prising an upper tubular section having a partition and openings at either side thereof, and a lower tubularsection having openings. therein, a valve located within said stopper, a valve seat formed on the lower section, a weighted member arranged within the saidupper section, comprising a ball and a receptacle therefor, a spring interposed between said valveand said weighted member, a second weighted memberjconsisting of a ball arranged in the said lower section, said weighted members being arranged to operate upon the valve alternately when the bottle is held upright or inverted.

3.-In combination with the bottle, an emptying stopper inserted therein, and comprising an upper tubular section-having a partition and openings at either side there of, and a lower tubular section having openings therein, a valve located .within said stopper, a stem formedon said valve and having a bead thereon, a valve seat formed in the. upper edge of said lower section, said valve having arecess' and a spring seated therein, a cupped member engagingone end of said spring, and a weight carriedby said cup.
